History

• With the majority of the cellular phone industry in 2010 utilizing a 3rd generation (3G) network, new worldwide standards have been created to encompass all multimedia aspects associated with it. 3GPP (3rd Generation Partnership Project) and 3GPP2 (3rd Generation Partnership Project 2) are the new standards for creating and distributing multimedia over 3G networks. These standards aid to provide consistent and uniform delivery from phone to phone, no matter the carrier or manufacturer.
  
  

Uses

• The .3g2 file extension is a common multimedia file utilized by cell phones that meets the standards of 3GPP and 3GPP2. A .3g2 file can represent many things, including music, video, broadband television, news feeds or any other streaming multimedia.
  
  

Origin

• The 3GPP and 3GPP2 standards were based on Apple QuickTime's software which utilized an MPEG-4 standard. Thus .3g2 files can be played back on computers using QuickTime 6.5 and higher as well as on any 3rd generation cellular device that provides multimedia playback.
